Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor lighting fixtures, such as bollard lights, do not provide effective wireless communication coverage in areas like walkways and pathways, where users need connectivity for their devices.
Innovation Solution
Integration of a plurality of directional antennas within the bollard light fixture's housing, configured to radiate and receive RF signals, connected via coaxial cables to a radio, providing a quasi-omnidirectional coverage pattern using a 4-port access point and splitters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If directional antennas are integrated within the bollard light housing, then wireless communication coverage is provided along walkways and pathways, but the housing structure must accommodate additional components increasing complexity
Solution Approach 1:
The patent combines multiple directional antennas within a single bollard light housing, merging the lighting function with wireless communication functionality. This integration allows the housing to serve dual purposes: providing illumination and delivering wireless coverage along walkways and pathways, thereby resolving the contradiction between enhanced adaptability and increased structural complexity.
Solution Approach 2:
The bollard light housing is designed to perform multiple functions simultaneously - traditional lighting and wireless signal transmission. By making the housing universal and multi-functional, the patent achieves wireless communication coverage without requiring separate infrastructure, thus improving adaptability while managing complexity through functional consolidation.
2Reliability
If multiple directional antennas are used to achieve quasi-omnidirectional coverage, then wireless signal propagation is improved in all directions, but the number of components and installation complexity increases
Solution Approach 1:
The patent employs multiple segmented directional antennas arranged within the housing to achieve quasi-omnidirectional coverage. Each antenna serves a specific directional segment, and collectively they provide comprehensive wireless signal propagation in all directions. This segmentation approach improves reliability of coverage while organizing complexity into manageable directional units.
Solution Approach 2:
The patent transitions from single-directional to multi-directional antenna arrangement by adding spatial dimensionality within the housing. By positioning antennas at different orientations and levels, the system achieves three-dimensional signal coverage, improving reliability while distributing component complexity across multiple spatial dimensions.
